I have a 4" cast iron vent from my toilet (with one sink vent going into it) that goes straight up to the roof (1 story bldg). I would like to recapture some of the space it goes through so I'd like to cut it, convert it to ABS, run it horizontally about 24 inches, up about 48", then another right angle back to join the original cast iron just below where it goes through the roof.
There are some questions I have about doing this...
1. Ok to run the toilet vent horizontal for 2 feet?
2. What's the best kind of adaptor (cast iron to ABS)?
3. Can I use either black or white(thiner) plastic pipe?
4. Can I reduce the plastic pipe down to 2"?
5. Will the adaptor(s) become a weak spot over time, subject to leaking and smells?
6. Should I continue with the plastic pipe up through the roof, instead of reconnecting to the cast iron pipe?
7. Ok to cut and adapt the cast iron pipe around the level of top of the toilet tank?...it's a standard 2 piece toilet.
That's all I can think of right now, but I'd appreciate any advice, especially if someone thinks this is not the correct way to do this.
